Book Description
It is now well appreciated that the immune system, in addition to its traditional role in defending the organism against pathogens, communicate in a well-organized fashion with the brain to maintain homeostasis and regulate a set of neural functions. Perturbation in this brain-immune interactions due to inflammatory responses may lead to psychiatric and neurological disorders. Microglia are one of the essential cells involved in the brain-immune interactions. Microglial cells are now not simply regarded as resident tissue macrophages in the brain. These cells are derived from myeloid progenitor cells in the yolk sac in early gestation, travel to the brain parenchyma and interact actively with neurons during the critical period of neurogenesis. Microglia provide a trophic support to developing neurons and take part in the neural wiring through the activity-dependent synapse elimination via direct neuron-microglia interactions. Altered microglial functions including changes in the gene expression due to early life inflammatory events or psychological and environmental stressors can be causally related to neurodevelopmental diseases and mental health disorders. This type of alterations in the neural functions can occur in the absence of infiltration of inflammatory cells in the brain parenchyma or leptomeninges. In this sense, the pathogenetic state underlying a significant part of psychiatric and neurological diseases may be similar to “para-inflammation”, an intermediate state between homeostatic and classical inflammatory states as defined by Ruslan Medzhitov (Nature 454:428-35, 2008). Therefore, it is important to study how systemic inflammation affects brain health and how local peripheral inflammation induces changes in the brain microenvironment. Chronic pain is also induced by disturbance in otherwise well-organized multisystem interplay comprising of reciprocal neural, endocrine and immune interactions. Especially, early-life insults including exposure to immune challenges can alter the neuroanatomical components of nociception, which induces altered pain response later in life. Recently the discrete roles of microglia and blood monocyte-derived macrophages are being defined. The distinction may be further highlighted by disorders in which the brain parenchymal tissue is damaged. Therefore, studies investigating the dynamics of immune cells in traumatic brain injury and neurotropic viral infections including human immunodeficiency virus, etc. as well as neurodegenerative diseases such as amyotrophic lateral sclerosis are promising to clarify the interplay between the central nervous and immune systems. The understanding of the histological architecture providing the infrastructure of such neuro-immune interplay is also essential. This Frontiers research topic brings together fourteen articles and aims to create a platform for researchers in the field of psychoneuroimmunology to share the recent theories, hypotheses and future perspectives regarding open questions on the mechanisms of cell-cell interactions with chemical mediators among the nervous, immune and endocrine systems. We hope that this platform would reveal the relevance of the studies on multisystem interactions to enhance the understanding of the mechanisms underlying a wide variety of neurological and psychiatric disorders.

Book Description
A translational overview of neuroimmune diseases for neuroscientists and clinicians that clarifies the pathological mechanisms underlying neuroimmune diseases and builds a comprehensive bridge between the latest research findings and their clinical implications in daily practice. The material is presented in two steps. The first section comprises a review of the pathogenic actions of immune cells in brain diseases. Here the authors discuss the mechanisms through which immune cells disrupt the functions of nerve cells. The second section explores the ways in which the brain becomes dysfunctional due to impaired nerve cell function. Based on pathogenesis, diagnostic and therapeutic strategies are discussed for each clinical category. The book will be invaluable for use in clinical practice of neuroimmune diseases

Book Description
Edited and authored by a wealth of international experts in neuroscience and related disciplines, this key new resource aims to offer medical students and graduate researchers around the world a comprehensive introduction and overview of modern neuroscience. Neuroscience research is certain to prove a vital element in combating mental illness in its various incarnations, a strategic battleground in the future of medicine, as the prevalence of mental disorders is becoming better understood each year. Hundreds of millions of people worldwide are affected by mental, behavioral, neurological and substance use disorders. The World Health Organization estimated in 2002 that 154 million people globally suffer from depression and 25 million people from schizophrenia; 91 million people are affected by alcohol use disorders and 15 million by drug use disorders. A more recent WHO report shows that 50 million people suffer from epilepsy and 24 million from Alzheimer’s and other dementias. Because neuroscience takes the etiology of disease—the complex interplay between biological, psychological, and sociocultural factors—as its object of inquiry, it is increasingly valuable in understanding an array of medical conditions. A recent report by the United States’ Surgeon General cites several such diseases: schizophrenia, bipolar disorder, early-onset depression, autism, attention deficit/ hyperactivity disorder, anorexia nervosa, and panic disorder, among many others. Not only is this volume a boon to those wishing to understand the future of neuroscience, it also aims to encourage the initiation of neuroscience programs in developing countries, featuring as it does an appendix full of advice on how to develop such programs. With broad coverage of both basic science and clinical issues, comprising around 150 chapters from a diversity of international authors and including complementary video components, Neuroscience in the 21st Century in its second edition serves as a comprehensive resource to students and researchers alike.

Book Description
Non-coding RNAs (ncRNAs), and in particular microRNAs are rapidly becoming the focus of research interest in numerous basic and translational fields, including brain research; and their importance for many aspects in brain functioning merits special discussion. The wide-scope, multi-targeted and highly efficient manner of ncRNA regulatory activities draws attention to this topic by many, but the available research and analysis tools and experimental protocols are still at their infancy, and calls for special discussion given their importance for many aspects in brain functioning. This eBook is correspondingly focused on the search for, identification and exploration of those non-coding RNAs whose activities modulate the multi-leveled functions of the eukaryotic brain. The different articles strive to cover novel approaches for identifying and establishing ncRNA-target relationships, provide state of the art reports of the affected neurotransmission pathways, describe inherited and acquired changes in ncRNA functioning and cover the use of ncRNA mimics and blockade tools for interference with their functions in health and disease of the brain. Non-coding RNAs are here to stay, and this exciting eBook provides a glimpse into their impact on our brain’s functioning at the physiology, cell biology, behavior and immune levels.

Book Description
The current book is focussed on the Toll-like receptors (TLRs), which are the first pattern recognition receptors (PRRs) discovered in humans. For example, TLR4 was first recognized in humans in 1997 as a PRR recognizing the Gram-negative bacterial lipopolysaccharide (LPS). This discovery revolutionized the field of innate immunity and filled the long-standing gap in the pathogen recognition by the immune system. Now, it is well established that humans have 10 (TLR1-TLR10) and mice have 12 (TLR1-TLR13) functional TLRs, excluding TLR10 that is present as a defective pseudogene. TLRs are present as both membrane-bound extracellular (TLR1, TLR2, TLR4, TLR5, TLR6, and TLR10) and intracellular (TLR3, TLR7, TLR8, and TLR9) PRRs in humans, which identify different pathogen or microbe-associated molecular patterns (PAMPs or MAMPs) and death or damage-associated molecular patterns (DAMPs) released by the host cells. A lot of development in the TLR biology has occurred in last 24 years since there first discovery in humans. The book is intended to describe their role in the host defence, human reproduction, non-infectious sterile inflammatory conditions, including brain immunity and cerebrovascular diseases, signaling mechanisms, adaptive immunity, and their targeting for drug development.

Book Description
Neuroimmune pharmacology seeks to harness the immune system to provide pharmacological intervention to combat neurodegenerative diseases. This book provides a comprehensive overview of topics that embrace the link between the immune system and the pathogenesis of neurodegenerative disorders. Results from recent studies strongly suggest that a major part of the process in diseases including Alzheimer’s and Parkinson’s as well as Prion diseases, comes from changes in the innate and adaptive arms of the brain and peripheral immune systems. Thus, the book provides an in-depth study of numerous fields including immunology, pharmacology, neuroscience and neurovirology. It is accompanied by a CD-ROM that includes access to lectures, slide presentations, and question and answers on neuroimmune pharmacology.
